Auxbeam B21 Series 3157 LED Bulbs Amber Yellow Built in Resistor CANBUS Error Free Anti Hyper Flash 3457 4157 Bulb 600% Super Bright Turn Signal Light, Need Resistors for Some Trucks

I recently upgraded the OEM incandescent bulbs in my 1999 Silverado 1500 Z-71 to these LED turn signal bulbs, and the results have been fantastic. The LEDs fit perfectly into the front turn signal sockets and work flawlessly—installation was a breeze. One concern I had when switching to LEDs was the potential for hyper-flash. Thankfully, the built-in resistor on these bulbs effectively prevented any hyper-flashing, which was a huge relief. The lights blink at the correct speed, just like the OEM bulbs. For the rear turn signals, I opted for a different brand of LEDs, the iFunyLED 4PCS 3157 LED Bulbs. These are also available on Amazon, and I chose the red lights. I’m pleased to report that I didn’t experience any hyper-flash issues with them either. I tested the functionality with the headlights on, when the brake pedal was depressed, and even with the hazard lights flashing. Everything worked perfectly—no issues at all. I also used the red iFunyLED LEDs as replacements for the brake lights, and they’re performing great. This combination of front and rear LEDs is completely compatible and works seamlessly across all signals and lighting functions. Overall, I highly recommend these LED bulbs for anyone looking to upgrade their 1999 Silverado 1500 turn signals. They’re bright, energy-efficient, easy to install, and, most importantly, they eliminate the dreaded hyper-flash. A solid upgrade that I’m very pleased with!

They make great reverse bulbs if you actually want to see what's behind you at night. My tail lights fit these bulbs well but they are long. No canbus errors, and they dont flicker.

These work reasonably well, no hyperflash on my 2012 Honda. They are well built and seem pretty sturdy, fans are dead-silent. My only issue is that they are not as bright as a previous set of 1157's I was using. UPDATE: After being able to drive a bit more at night, I find that the marker-lite mode if these is actually just a bit more subtle than the previous 1157's I had. Its still quite visible and clear, far beyond any halogen bulb. The turn-signal mode is very bright, on-par with the previous ones I had. Giving 5 stars now, definitely worth it.

These Auxbeam B21 Series 3157 amber LED bulbs are no joke. Installed them as front blinkers and now my turn signals don’t just flash they declare intent. Out here in Alaska nights, where everything is already dark and moody, these cut through like a warning beacon. No mistaking what I’m doing anymore. Even people who “didn’t see me” definitely see me now. Built-in resistor worked as advertised no hyperflash, no drama. Just clean, crisp, bright amber hits that feel way more serious than factory bulbs ever had business being. Honestly, it feels like my truck went from “I might turn” to “stand by for official announcement.

These are not compatible when used in a 2020 Toyota Tacoma. When in the DRL mode the turn signal light flashes rapidly as if the bulb is burned out. Also when the lights are first tuned on in the DRL mode the lights are bright for a few seconds then they dim down.

Initially great! Brighter than other LED tail/turn lights that I have tried in my '16 F350. Also, they don't induce hyper flashing like some others do. Hopefully they last a decent amount of time. I'll report back if they do. So far, I am very pleased!

Works without hyperflash. And is bright👍🏼

Wow they are extremely bright. I installed it on my Lexus 2013 GS 350. Works great. Except that they are a little bit longer, slight challenge on installing but managed to make it work. Am so happy. Highly recommended. Another great product from Auxbeam. I bought also the DS4 led upgrade for HID . So satisfied.

It’s very bright and it doesn’t hyperflash so far but the beam aim is more into sides not to the front like 270 degree of light not as much as halogen bulb flashes 360, I hope it’s clear enough and understandable.

Se instalaron en sentra 2021 sense, plug and play, los cuartos dan una ligera luz más intensa vs los focos de filamento por que solo enciende una seccion de todos los LED, el cambio más notorio son con las intermitentes o las direccionales encienden todos los LED restante y genera un destello muy bueno, la instalación es rápida y sencilla, espero que duren mucho tiempo y por el momento quedo satisfecho, muy recomendable, actualizare en caso de que fallen
